MeshGrid coordinates decentralized Bluetooth & LoRa mesh networks — BitChat and Meshtastic — so communities stay connected during outages, floods and disasters. No internet. No towers. No SIM. Just the devices around you.
Every phone and LoRa radio becomes a relay. This simulation visualizes how overlapping coverage zones knit remote kampung, towns and rescue teams into one resilient fabric.
Meshtastic runs on affordable LoRa boards. Configure the region correctly so you stay within Malaysian regulations — always use the 919–923 MHz ISM band.
Choose a Meshtastic-compatible board such as a Heltec V3 or LILYGO T-Beam. Ensure it ships with an 868/915 MHz antenna suitable for the Asian band.
Open the Meshtastic Web Flasher in Chrome, connect over USB and install the latest stable firmware. No coding required.
In the app, set LoRa region to MY_919. This keeps transmissions inside Malaysia’s licence-free band and legal power limits.
Share a channel name & key with your community. Every node now relays messages up to several kilometres — extending reach with every device.
